The arrangement for forming the cigars and cigarillos is also mounted onthe frame 2. On a bracket 3D connecting the two-frame parts 3 and issecured by two bearings (not shown) the supply-spool 32. On this spoolis wound the tobacco covering strip 3d and the auxiliary strip 35preferably made of paper. The two strips 3d and 35 run between two guidepulleys 35 and si@ and across an adhesive device i2 mounted on thebracket 35. The covering strip 34 and the auxiliary strip 35 then movetogether over pulley 134i mounted on a shaft pivotally secured in theplate 'l of the frame 2. The two strips 3d and 36 then move beneath thetobacco charge coming from the bridge 25, and the strips and the tobaccofilling then move together into the inlet-funnel 28. On this part of theplate 'i is guided a shaping-belt i5 running over the pulleys fili, 55,and 52 and driven by the driving roller 5d, as is shown more in detailin Figs. 4 and 5. The driving roller 5d may be driven by convenientmeans as an electric motor or the like (not shown). The shaping belt l5takes up the tobacco charge lying on the two strips 3d and 35 and pullsthe strips and the charge through the inlet-funnel 28 to the shapingchannel 55. This channel is overlapped by the shaping members 55 and ii@(see Fig. 5) rounded on their inlet-portions 5?. and Gil. These shapingmembers 53 and 5l) are secured by bolts 53 and 55 or the like to thechannel 55. In Fig. 'Z there is shown a section taken on line VII-VII ofFig. 4i illustrating the overlapping of the two shaping members.

After leaving the shaping members 5t and 50 the combination of tobaccocharge 23, covering strip 34, auxiliary strip 35, and shaping belt 45moves through the outlet-finger 55 to the seam smoothing iron 5S whichmay be electrically heated. The outlet finger 55 is shown more in detailin Figs. l, 5 and 8 and has a bridge part 51 secured by bolts 59 to theshaping channel 55. The smoothing iron 56 is shown more in detail inFig. 9 and may be provided with a smoothing edge 'll heated by a device'i3 in convenient manner, such as by electrically energized windings orthe like (not shown). Having passed the smoothing iron S8 the auxiliarystrip 36 and the shaping `belt 4S are separated from the tobacco chargesurrounded by the covering strip 35. The auxiliary strip 36 is thenwound on the storage spool it positioned on the frame part 5 in anyconvenient manner. The shaping belt 4S returns over the driving roller54 and is ready for further use.

The tobacco charge 23 surrounded by the f sealed covering strip 3d movesto a cutting device generally marked by the reference number l2 shownmore in detail in Fig. l0. The cutting device comprises an eccentricknife 14 pivotally mounted on a shaft 'l5 secured in bearingsconveniently xed in the casing 18 shown in section in Fig. 1G. The shaftis driven by convenient means, such as an electric motor or the like(not shown). The knife 14 moves into a slot 80 in a tube composed of thetwo portions 82 and 84. The tobacco charge 23 surrounded by the sealedcovering strip 31E passing the tube 82, tf1 is cut by the knife 'M- andthe cut portions thereof as cigars and cigarillas are pushed out onto aconveyor 85 arranged at the end of the machine. The cigars or the likemay be transported through the conveyer 55 to a packing machine.

The operation of the machine described above is as follows:

The cut tobacco falls from the feeder 4 onto the conveyor 6 and issupplied to the chute 8. From the chute the cut tobacco slides onto theconveyer belt l2 guided in the U-shaped channel member I8. In thischannel member lil and between the pressing wheels 22 and 24 and thepressing plate Z5 it is formed to a strand or rope which is forwarded bythe conveyer belt I2.

On the storage spool 32 the tobacco strip 34 and the auxiliary strip 35are wound so that the auxiliary strip which may be made of paper, liesbeneath the corresponding portion of the tobacco strip 34. The width ofthe strips is such that the tobacco strip overlays the auxiliary stripon one side about 2 mm. The width of the tobacco strip is a littlegreater than the circumference of the cigar or like to be made. Theguiding of the two strips is such that the pull exerted by the shapingbelt i6 is always transmitted to the auxiliary strip 35, i. e. thisstrip lies on the guiding pulleys :ill and llt respectively.

Through the pulleys 3B, 49 the combination of the two strips 3, 35 movesto the adhesive device 42. The wheel 53 dipping into a containercontaining an adhesive material applies an adhesive seam to the edge ofthe tobacco strip 311 supported by the auxiliary strip 36.

The combination of the two strips 313i and 35 meets the tobacco chargecoming from` pressing device 22, 24, 25 and running through the bridge25 on the inlet-pulley its. The tobacco charge combined with the twostrips enters the shaping channel 5G the raised sides of which bend theedges of the strips upwardly. The upwardly bent edges of the stripsenter the shaping menibers 58 and 55. These overlapping members bend thestrip edges one upon another. The holding together of the tobacco chargeis insured by the inlet-funnel 28, as is shown in more detail in Fig. 5.The overlapping of the strip edges is illustrated in Fig. *l from whichit may be seen that one edge of the strips is beneath the member 55while the other edge is between the members 58 and 50. The strip edgeslying between the members 58, 55 are correctly registered and theunderlying tobacco strip on its inner side is provided with the adhesiveseam. The other strip edges underlying the member Eil are not correctlyregistered because the auxiliary strip edge is narrow relative to thetobacco strip. In leaving the shaping members 58, 55 the tobacco stripedge provided with adhesive seam therefore lies directly on the othertobacco strip edge. ln this condition the tobacco charge surrounded bythe two strips enters the seam smoothing iron 58 which effects thesealing of the longitudinal seam. After sealing the tobacco strip 34,the shaping belt 45, and the auxiliary strip 35 pass over the pulley 52.Now the length of the tobacco strand moves to the cutting device 'i2 andis out oii and finally removed by the conveyer as finished cigars andcigarillas. The cut off cigars, cigarillas, stumps or the like can alsobe further processed, as for example, 4they may be provided and shapedwith a wrapping. it is also possible to lead the uncut length furtherand enclose it with a wrapping strip in a like or similarly con structedmachine before cutting up.

From Fig. 1 it is to be observed that all posin tions of change ofdirection through which the covering strip and auxiliary strip passtogether are so disposed that the auxiliary strip traverses the shorterpath, that is to say, lies on the inside. This arrangement offerssubstantial advantages and is distinguished from the path of the paperstrip in the case of cigarette machines.

While we have described and shown in the foregoing specification anddrawings a preferred embodiment of the invention, it will be understoodthat many changes and alterations may be effected without departing thescope of the following claims. For instance, all moving parts, asconveyer 6, driving roller 20, driving roller 54, cutting knife T4,spool 10, and conveyer 86 may be driven by a common driving device as anelectric motor or they may be driven by separate motors suitablysynchronized.
